hello! we have this used machine imported from EU and it's throwing this code permanently. i now what this error means (rom contents error/ incorrect firmware).
tried update firmware, tried Nvram reset ( a145fw), but no luck . didn't replace PRCB yet. i suspect PRCB is deffective because when trying to update firmware only mfp board and scanner appears in update firmware screen. no matter what firware i'm trying( some just to see if prcb update appears). even with the first firmware release. the machine is correctly seen as 3A (A5AY by SN). any idea to try before ordering PRCB board? after some research on web, found something like to try reinstalling firmware only for prcb? i have acces to infohub but i'm out of ideas after three days...
